This study investigated the structural coloration and fabric hand of the caustic reduced fabrics for emotional garment using structural color yarns, which was spun by 37 alternating nylon and polyester layers capable of producing basic colors using biomimetic technology. The colorations of the three kinds of structural color yarns were confirmed using multi angle spectro-photometer, and their triangular cross sections composed with 37 alternating nylon and polyester layers were measured using SEM and were discussed with layer length in relation with coloration and spinning conditions were also set up. The apparent color difference and reflectance of the three kinds of fabrics with different density and weave pattern were analysed as ranging from 400nm to 700nm. The optimum fabric structural design which is made by warp and weft densities(194ends/in ${\times}$ 105picks/in) and caustic reduction condition by $100^{\circ}C$ temperature and 60minutes with NaOH, 20g/l solution were decided through analysis of the mechanical properties and fabric hands of these three kinds of fabrics treated with 3 kinds of the caustic reduction conditions. And it was shown that the rate of caustic reduction was increased from 13% to 23% with increasing temperature and time of caustic reduction. The extensibility, bending rigidity and shear modulus of caustic reduction treated fabrics were decreased by treatment of caustic reduction, on the other hand fabric compressibility was increased. And it was shown that the hand value of specimen number one which was treated with temperature $100^{\circ}C$ and time 60minute was the best and the hand of this fabric was better than that of Morpho $fabric^{(R)}$ made by Teijin co. Japan.

The subject, in the blouses that sleeve caps and sleeve lengthes are different from, did sensory test by right arm movement and both arms movement. This sensory test which is used in fabric good, is Shef's. RESULTS : 1) The ease of bust size is very significant by cap height, at 5%, 1% level by sleeve length. 2) The front area of arm hole is affected by cap height, sleeve length movements more than the back and the under area of arm hole are 3) Sleeve width is affected by cap height, sleeve length both arms movement. That is, they should be designed according to the use because they affect the ease of blouse very much. Especially bust size should be considered with sleeve pattern because the ease bust becomes different with sleeve pattern.

The purpose of this study was to develop a system by which the tensile properties of knitted fabrics can be applied. In this study, 3 different conditions of tensile property were tested on 8 sample fabrics with various stitches and stretch ranges. The subjects were five women of age from 18 to 24 years showing average body figures. The major findings derived from this investigation were as follows: The tensile properly of 12gf/cm was considered as appropriate for applying into the pattern alteration in the case of moderate stretch(course, $25\~35\%$) or over samples. However, for the stable stretch(course, under $20\%$) fabrics, such as Milano rib stitch, a tensile properly of 20gf/cm was regarded as more valid.

The data were obtained from market research of 12 department stores which were located in Seoul, Daegu and Busan, and from questionnaires completed by 356 women in Daegu area whose age was 20 years and older. The SPSS package was used for data analysis which includes frequency, percentage, $X^2$test, ANOVA, and Scheffe test. Cotton was the most popular fiber for coverings and fillings. Color preference was in the order of pastel, non-chromatic, vivid, and white color and pattern preference was in order of floral, check, and stripe pattern. Practicality, color and fabric were the most important factors and price was the most unsatisfied factor when bedclothes were purchased. Also, information for bedclothes was obtained mainly through internet shopping, home shopping or catalog shopping.

This study examined textiles used for ancient costumes of the $16{\cdot}17th$ century in Joseon period, focusing on fabric types and patterns of the costumes from tombs. The purpose of this study was focused on investigating the relationship between fabrics and social backgrounds, especially change in using fabrics through the war from Hidyoshi's Invasion of Korea in 1592. Since the war must have had an effect on the life of people's. The result of the study is that silk occupies $69{\%}$ of all textiles, and cotton, linen follow The weaving method of silk was primarily Plain and satin weaves. However the use of twill, gauze, and double weave, that had led weaving methods of silk during the Koryo Period, were considerably decreased in Joseon Period. Types excavated fabrics in the $16{\cdot}17th$ century Joseon period can be said various. Of this, silk was the most remarkable one till Hidyoshi's Invasion of Korea in 1592, when the ratio of patterned silk dramatically decreased. Contrarily, the ratio of cotton and plain fabric increased rapidly in Hidyoshi's Invasion of Korea in 1592. It is supposed that the result is largely due to unusual condition of the war time. After the war, it is estimated that use of pattened fabric as well as silk was decreased. Patterns of textile fabrics in $16{\cdot}17th$ century were various. In result of surveying a trend of increment and decrement, it is known that the ratio of patterned textile fabrics decreased dramatically in Hidyoshi's Invasion of Korea in 1592 and Manchu war of 1636. Tendency of textile use by social Position is more notable. It is appeared that a lot of silk fabrics were used in High hierarchy. The excavated remain and ratio of silk were the highest in Kyonggi Province including Seoul.

In ancient China, Su(綬) was the ornament of the full dress. It had originated from tying the jade or another thing before Jen(秦:Qin) dynasty and it tied the imperial jade seal and the chop from Han dynasty. Su of Han dynasty was different in the inscape, colour, length and density according to the grade. And the shape was the straight line. But these phenomena were changed after Han dynasty. This study showed how it changed. To studying used the comparison method of literature records, paintings and archeological relics. It mostly studied imperial Su. Su of Han dynasty of the high grade was formed by Yeok, the circle type jade and Su(Su moaned whole Su, at the same time moaned the part of Su, too). Afterward, Yeok was changed into Small Su[小綬] and Su was changed into Big Su(大綬). Originally the circle type jade was connecting Yeok to Su, but it was changed into tying Small Su only. Su of Han dynasty used the four kinds of colour, but from Su(隋: Sui) dynasty used the six kinds of colour. Originally Su was interlacing, but it was changed into the silk fabric from Song[宋] dynasty. According to using silk fabric's Su, it was likely to disappear the system distinguishing the grade by length. And it kept the method of interlacing the reticulation in the low part of silk fabric's Su. So, after using silk fabric's Su, the system of the density was not about the main body but about the reticulation. Su was been used woven with supplementary golden wefts, too. The circle type jade was chiseled the dragon and cloud from Geum[金:Jin] dynasty. These not the pattern of silk fabrics.

In the direct digital textile printing process, the pre-treatment process is an essential condition for products by forming a clear pattern by sticking and penetration of DTP dye without spreading on the fabric. Recently, pre-treatment agent is changing from high viscosity to low viscosity in order to reduce defects of fabric during pre-treatment process. In this study, pre-treatment agent of acrylic polymer with low viscosity(less than 50cps) was prepared according to the solid content of the polymer, pre-treated on the cotton fabric, and direct DTP printing was performed to compare the color and sharpness. As a result, it showed high color at a viscosity of 50cps or less. When the solid content of the polyacrylic acid having a high molecular weight(A1) was 2.5wt%, when the solid content of the polyacrylic acid having a low molecular weight(A2) was 1 - 1.5wt%, the color was the best. And when the solid content of A1 and A2 was 1.5wt%, the degree of spreading was small and A1 was superior to A2 at the sharpness.

Baekje patterned Pyojihwajomoonkeum is a fabric that expresses Baekje's unique culture possessed by Shosoin(正倉院) in Japan. Reflecting the close exchange relationship with the Chinese Southern Dynasties, these patterns are suitable as good examples to grasp the forms and atmosphere that prevailed during that era. Through the analysis of many pieces, it has been identified that the patterns were unique to Baekje. With an aim to ascertain and restore the original form of Pyojihwajomoonkeum, designs were proposed utilizing Pyojihwajomoonkeum as a form of storyteller clothing that fits the modern sense. Fabric was designed by continuously repeating the colors and patterns of Pyojihwajomoonkeum upward, downward, leftward, and rightward and woven with a Jacquard loom. The fabric woven was dried, processed, and used to make a total of four pieces of storyteller clothing consisting of men's wear, comprising a jeogori and pants, and women's wear comprising a jeogori and skirt. The top jacket was long enough that the hip is covered. It has wide sleeves and linear decorations were attached to the collar, lower edge of sleeve, and bottom hem. The pants are wide legged, the top is wide, and the bottom hem had linear decorations attached. What is the most important when using the original form of a traditional culture is processing the raw materials following cultural traditions to create value. Costumes of an era are the combination of individual elements and represent the culture of that era. Therefore, a consideration of the origin and prevailing ideas of the era must be considered. It is anticipated that this paper will serve as a basis for leading such a process, followed by studies on the utilization of the original form of Baekje culture.
